Answer:
Step-by-step explanation:
The perimeter is all the side lengths added together
In this case, the
perimeter = x + (x+4) + (x+6) = 3x + 10
The correct answer is the first choice
Very good job! They are all correct and it shows how you got the answer! ^_^ 100%
Hello!
We can solve this by using substitution
we can plug y = x - 1 into the other equation
So 2x - 3( x - 1) = -1
We can distribute the -3 to (x - 1)
2x - 3x + 3 = -1
Combine like terms
-x + 3 = -1
Subtract 3 from both sides
-x = -4
Since x is negative we can multiply both sides by -1
x = 4
We can plug x into the first equation
y = (4) - 1
y = 3
The answers are x = 4 and y = 3
Hope this helps!
If 3 cups is 20% of the whole mixture, then you multiply both numbers by 5 to find the total amount of juice. 3•5=15 cups of juice
